For those without *.crx for Chrome association you can launch Chrome with this parameter:
--load-extension=/home/avar/g/sight/
After having cloned sight.git into ~avar/g/ obviously. And as a suggestion to the author: Getting it into the Google Chrome Extension listing would make this even easier.Edit: Just read http://twitter.com/tsenart/status/26366227841 that sucks, Google.
